FEED MECHANISM.

To all whom it may concern Be it known that I, Mioimnt Bnoonn, a citizenof the United States, residing at Grand Rapids, in the county of Kentand State of Michigan, have invented new and useful Improvements in FeedMechanisms, of which the following is a specification.

My present invention relates to feed mechanisms, particularly to such asare used with woodworking machines; and its object, generally, is toprovide mechanism of that character, which shall be simple andeconomical in construction and easy and effective in operation; and moreparticularly, which shall have removable, replaceable andinterchangeable work -engaging parts, in order that, becoming worn, theymay be removed and replaced with others, and also in order that,becoming unequally worn interrelatively, they may be interchanged tosecure a desired uniformity of wear throughout; and also to provide amechanism of that character, in which said parts shall be severallyrelieved from all working stress during a portion of the mechanismsoperation; and also to provide mechanism of that character which shallbe variously improved as hereinafter appearing. These objects areattained by, and my invention finds a preferable embodiment in, thestructure hereinafter described, and illustrated by the accompanyingdrawings, in which:

Figure 1 is a front elevation of my feed roll with portions of connectedparts and shown partly in vertical longitudinal section: Fig. 2 is anenlarged detail view of a portion of the same: Fig. 3 is a view inperspective of one of the work -engaging members annular carriers: Fig.4 is a similar view of one of such work-engaging members; Fig. 5 is alike View of a retaining clip for such members; Fig. 6 is a longitudinalsectional view of one of said carriers taken on planes in which thesockets for said members do not lie, and illustrating the annular groovein each face of the several carriers; and Fig. 7 is a fragmentarysimilar view of such a carrier, illustrating variant means for retainingsaid members in their sockets.

A feed shaft 1, suitably journaled at 2, 2 and driven as by its gear 3,is provided with a plurality of encircling removable annular carriers 4,held side by side thereon by suit- Specification of Letters Patent.

able means, as the collar 5 toward one end of the shaft and the nut 6threaded thereon toward its other end. .The material oper ated on, orthe work,as a wooden board 7,-is fed by my feed roll, between it and anysuitable cooperating member, as the work-sustaining roll 8.

Each carrier 4 is provided with radiallyextending worlcengaging members9, preferably rcsilient,as rubber-and adapted to alone engage my feedrolls side of the work in the feed operation. These members arercmovably inserted into sockets 10 in the sides or faces of thecarriers, such sockets having overhanging outer edges, as shown, tosecurely hold such members in position.

Annular grooves 11, formed in the sides or faces of the carriers andopening from the bottom of the sockets, permit expansion of the saidresilient members thereinto when operatively engaging the work. Thesockets on one side of each carrier are alternately disposed to those onthe other side as shown, in order that the carriers may not be undulyweakened by the sockets and yet that the carriers may afford acircumferentially unbroken surface engaging the work. The shaft 1 has akey 12 and the carriers have corresponding key ways 13 so that thecarriers will be rotated with the shaft, and yet may be longitudinallyremoved from it when desired: when so removed, the wire clips let whoseends are adapted to be inserted into orifices 15 in the carriers, orscrews 16, or any other suitable means may be provided to hold themembers 9 in their sockets.

It will be seen that the several members 9 are entirely relieved fromall working stress except when actually engaging the work, which in theconstruction shown is only about one eighth of the time,--whereby theresiliency of the rubber, etc, of which they are formed, is prolonged:also, it will be seen that when worn, these members may be removed andreplaced with others: and also, that when such members borne by certaincarriers (as those near the middle of the shaft) become worn more thanthose borne by other carriers (as those toward the ends of the shaft),the carriers may be removed longitudinally from the shaft, and replacedthereon in interchanged relation, whereby a uniform wearing of saidmembers is attained.

Not confining myself to details 01 construction shown or described, Iclaim:

1. A feed roll comprising a rotatable driving shaft, and a plurality ofcarriers concentric and separably connected therewith, each having asocket opening at the carriers side and having overhanging walls, and aworkengaging member carried by the carrier in the socket and extendingradially beyond the periphery of the carrier.

2. A feed roll comprising a rotatable driving shaft, and a plurality ofcarriers concentrio and separably connected therewith, each havingsockets on each side, the sockets on one side being alternately disposedto those on the other side, and having work-engaging members carried bythe carriers in the sockets and extending radially beyond the peripheryof the carrier.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
